GERHARDT J'. PATITZ AND CORNELIUS SIPPEL, OF CHICAGO, ILLINOIS, ASSIGNORS TO KAESTNER @c CO., .A CORPORATION OF ILLINOIS.

MANURE AND GARBAGE INCINERATOR.

To all who/m it may concern:

Be it known that we, GERHARDT J. PATITZ and CORNELIUS Sirrnn, both citizens of the United States, and both residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Manure and Garbage Incinerators, of which the following is a specification.

This invention relates to an improved construction in a crematory for the inciner' ation of garbage, manure, refuse, and other waste materials.

The essential object is to construct a cremator in such manner that the garbage or manure will be thoroughly and quickly cremated, which is accomplished by the provision of a separate drying chamber into which the wet garbage or manure is first dumped, and dried preparatory to being fed onto the main grate of the furnace for incineration.

Other objects will appear from the following description of the invention, which consists in the features of construction and combination of parts hereinafter describedI and claimed.

In the drawings, Figure 1 is a sectional elevation of this improved cremator; Fig. 2 an end view thereof; and Fig. 3 a transverse section, taken on line 3 3 of Fig. 1.

Referring to Fig. 1, an air blast chamber 4- is positioned in the bottom of the cremator, and has oppositely arranged exhaust ducts 5 and 6, respectively, the duct 5 opening beneath a furnace grate 7 over which is a lire arch 8 the space between the grate and arch constituting a lire chamber 8a. Oppositely arranged movable dampers 5a and 6aL control the travel of the forced air from the air blast chamber 4t. This arrangement permits air to be forced up through one or all of the grates, as desired.

A hollow bridge wall 9 is formed adjacent to the inner side of the grate 7, and a lower final combustion grate 10 is adjacent thereto, said grate preferably having interstices approximately three inches apart. Directly above the lower final. combustion grate 10 is an upper refuse 'grate 11, having, for practical purposes, interstices formed four inches apart, the space intermediate the two grates 10 and 11 constituting the lower end Specification of Letters Patent.

Application led April 26, 1909.

Patented Mar. 14, 1911. Serial No. 492,401.

of a combustion chamber 11a, the upper end of which extendsv between the grates 1l and 13.

Ash doors 12 open beneath the lower final combustion grate 10; fuel doors 12a open into the grates 7; and above the upper garbage grate 11 are lire arches 13 for directing the travel of the heated gases of combustion, so that they will act upon the walls of the drying chamber and serve to heat it. In other words, the arches 13 serve to retard the outward flow of the-heated gases and keep them conlined for a period of time within the combustion chamber, so that they serve to generate more heat;

A drying chamber 14, as indicated, is formed on one side of the cremator in elevated position, and has an outer swinging feed door 15 and an inner swinging door 16 actuated in any approved manner, and this chamber separates the manure or garbage from the original fuel bed so as not to quench or destroy the source of combustion. The drying chamber has usually a steel lined bottom which serves as an igniting arch for the furnace below and at the same time furnishes heat for drying the wet manure or garbage within. It is obvious that the manure or garbage can be fed into the drying chamber through its top wall instead of through the side doors. The arising vapors are drawn off through a vent hole 16a near the top of the chamber communicating with a flue leading to the smoke stack. After the greater part of the moisture in the manure or garbage has been evaporated in the drying chamber, the hinged doors are opened and the material is pushed onto the upper grate 11 for combustion.

The heated gases of combustion follow an upward path through the upper grate 11. upon which the waste material has been spread, and entirely reduces the same to a mineral ash which falls to the bottom of the combustion 'chamber for removal. The gases of combustion travel farther horizontally, again heating the walls of the drying chamber, and finally enter a vertical up and down flue 17 which is provided with a series of resistance or staggered baffle arches 18, which, when heated to a high temperature, arrest the minute particles for final combustion. As usual, a removable heavy -tial in cremating manure,

metal screen 19 serves to @arrest any t, sparks that might escape tothe atmosphere through the stack 20. Y

'If'ydesirech there may be a Vstench fire in the bottom of the stack, but itis not essen- The stench fire `grate is indicated at 21, above which is a fire door 22,and beneath is` an ash door 23, as usual; A cleaning door 9.4L is located in the vbottoni of the flue 17 beneath the staggered baffle arches 18. Staggered stench bars 25 are placed within Vthe flue 17 stench fire. c

AS "manure contains a great lan'io'unt of nitrogenous matter, and, owing to its ini- Y perviene nature', it becomes tightly packed in layers on Vthe grate, and as it is', in fact, Van insulator against heat or cold, this in- `'ventionfcontemplates the use of aVV hollow bridge` wall to permit the introduction of air' iinder-slight pressure, such as is furnishedby a fan blower; It vhasbeen found VVVthat a blower 'furnishes the necessary amount ofoXyg'en for combustion; that it breaks up and prevents the ytight packing of /inan'ure'in layers; and thatfit creatsa .higher temperature of combustion v within V'the furnace to more economically incinerat'egthe manure.

The provision of a v'separate drying chainber the wet manure-and garbage is of considerable importance, as it prepares the e waste material for incineration, rnone/of the fieshfwetj-material falling onto the primary fuell-b'e'd-and thus smotherin'g anddestroying-the source of combustion.. The drying chamber is shut olf from the upper garbage grate by means of hinged tile lined doors, whieharecounterbalanced and can be operatedfroin the outside, fori-protecting the operatorffroin the scorching-heat unavoidable `in constructions where the ,waste is dumped directly onto the grate-.Y What we' claim as new anddesire to secure by Letters Patent is: Y
